Alocasia Tandurusa (Tandurusa alocasia) care

Light

Bright but filtered. Alocasia Tandurusa burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Wants plenty of bright, filtered light to develop its dramatic leaf shape and dark veins. Shield from harsh direct sun, which bleaches and scorches the foliage; too little light produces small, pale leaves. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering alocasia tandurusa: when the top 2-3 cm of soil is dry, roughly every 5-7 days in growth. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep evenly moist but never soggy during active growth. Allow the surface to dry slightly between waterings and cut back markedly in winter, as wet, cold soil quickly rots the corm.

Soil and pot

Alocasia Tandurusa grows best in airy, fast-draining aroid mix. Use a loose blend of coco coir or peat with orchid bark, perlite and charcoal. Excellent aeration and drainage are essential; compacted, moisture-holding soil suffocates the roots and triggers rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Alocasia Tandurusa sits happiest at around 60-80% humidity and 18-29C (65-84F). Needs high humidity to look its best; dry air browns the intricate leaf edges. Use a humidifier or pebble tray and keep it away from draughts and heating vents. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed alocasia tandurusa sparingly. Feed every 3-4 weeks through spring and summer with a balanced liquid feed diluted to half strength. Pause feeding in autumn and winter while growth slows to avoid fertiliser salt accumulation in the pot. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on alocasia tandurusa in the Growli community. Each is annotated with the most common cause so you know where to start.

• Drooping leaves — Commonly underwatering or a sudden environment change; check soil moisture and stabilise light, warmth and humidity.
• Brown crispy edges — Low humidity or mineral buildup from tap water; raise humidity and flush the soil or use filtered water.
• Root or corm rot — From overwatering in dense soil; switch to a chunky mix and let the surface dry between waterings.
• Spider mites — Favour dry warm conditions; check leaf undersides regularly and treat at the first sign of stippling or webbing.

Propagation

Propagate by division and offset corms at spring repotting. Separate corms from the parent, pot shallowly in a warm, humid, lightly moist medium, and keep conditions stable while they root and break dormancy. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Alocasia Tandurusa is toxic to pets. ASPCA lists Alocasia as toxic to cats and dogs. Every part holds insoluble calcium oxalate crystals; ingestion causes oral burning, drooling, pawing at the mouth, swelling of the lips and tongue, vomiting and trouble swallowing. Keep away from pets and children. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
